| Abstract: |
| The modulation recognition technology for communication signals based on BP neural networks is studied. The character parameters reflecting the difference of signal modulations are extracted. According to convergence rate and right identifiable probability, the best neural networks classification is established. Experiment result shows that these technologies have better performances for automatic modulation recognition of communication signals. |
